Those are/were my thoughts as well.The screen alone will slow the air flow. It is his bike and I'm not going to criticize it either.

 

Stock configuration has the rear tube running uphill also, albeit not quite as much. I do believe that the oil/mist coming out of the breather will be sufficiently pushed uphill for that short distance.
This has been a work in progress, started last year with a simple extension of the tubes more deeply into the throat of the intake.
I should be able to get back on the bike tomorrow and try this latest version out.
I am not out to squeeze every last hp or ft.lb or toque out of this bike. If it runs properly and does not seem to be running rich, and my seat of the pants dyno is satisfied I'll likely keep this setup, though I may remove the screen if the clamps show no signs of moving, which they didn't last year in a previous iteration.
Alternative is to put the breather tubes back on and let the oily air enter the intake. I don't want to do that. So long as I don't see a quick buildup of oil in the can or a noticeable downgrade in performance due to air turbulence in the filter body I'll be happy with the mod.

 

The way OldMike did his is pretty clean. That's the way I'd do it. I'd run the hose to ground though... had enough of emptying catch cans.

 

Catch Can - Schmetz Cans just one more thing and more complications.
Oil comes from the ground - it's natural.

 

I agree now that after 375 miles it's just a bit of water vapor coming out of the hose, not worth collecting.

 

I hardly ever see anything under my hose; after long, hard interstate runs - when I stop for fuel I may see a drop or two of what looks like oil but it's oil and moisture.

 

Put 70 miles on my bike today. Performed flawlessly. A dyno may perhaps say it's not putting out what it could, but my seat of the pants model says it's doing just fine. I'll take the air cleaner and catch can off before I ride again and see if it's all working as it should.

 

Nothing in the catch can when I checked it this morning. Hoses showed a little condensation. Clamps remained in place. Maybe removing oil and leaving it a half qt. low on the stick has made the difference and will prevent as much blowby as I was seeing after the 1K service and prior to the Stage 1 and 2 install.

 

I bet it has more to do with the fact that the intake isn't sucking on the hose.

 

I hope that's exactly what it is!
